2.02am 01mm smcaa Isidore Jacoel, Norfolk; Va. Application July 21,1934, Serial No. man 10 Claims. (01. 140-121) My invention relates tonew and useful immovements in a cable splicer and has for its principalobject the provision of a device or the character described adapted forpractical and rapid execution of splices on cables of various kinds andespecially those used on modern aircrait construction.

Another object of the invention consists in the provision of a cablesplicer including a handle portion adapted to be clamped in a vise orthe like and a clamping member rotatably mounted relative to the handle,means being provided to resist rotation of the clamping member relativeto the handle and to overcome the torque of the cable. v

A further object of the invention resides in the provision of readilyremovable and replaceable clamping jaws, whereby different jaws may beused for diflerent sized cables, the jaws further being formed andadapted for use in splicing or wrapping either flexible or non-flexiblecables.

with the above and other objects in view, which will appear as thedescription proceeds, my. invention consists in thenovel details ofconstruction, and arrangement of parts, described in the followingspecification and illustrated in the ac-- companying drawings, and whileI have illustrated and described the preferred embodiments of theinvention, as they now appear to me, it will be understood that suchchanges may be made as will fall within the scope of the ap pendedclaims.

In carrying out my invention I.provide a handle indicated at l which hasan elongated recess 2 extending from one end and closed at the oppositeend by the wall or partition 3 having a semicircular opening 4. as shownmore particularly in Fig.8 of the drawings, for a purpose which will belater brought out. A flange or sleeve 5 5 extends outwardly from thewall or partition 3 and exteriorly the handle is formed with the flatportions shown at 2 adapted to be engaged by a vise or the like.Adjacent its upper end, above the flattened portions 6, the handle isformed 10 with the horizontal inwardly directed slit or slot shown at Iwhile a vertically extending slit or slot is shown at I, moreparticularly in Fig. 2 of the drawings, and leading to the slot 1thereby forming a yieldable portion 9, an outwardly di- 1 rected lug Itbeing formed on the end 01 the yieldable portion formed by thevertically extending slit or slot 2 and a corresponding outwardlydirected lug or projection II is formed on the opposite edge of the slitor slot 8. A screw 20 I2 having the .flnger engaging head It extendsthrough openings in the lugs or projections l0 and II and receives a nutI! so that by turning the screw, by engagement'oi the enlarged head 13,the yieldable portion 8 may be drawn in- 25 'wardly to clamp the post orrod ll, received in the opening 2 01' the handle I, and forming a partof a clamping member to be described, the engagement of the yieldableportion 9 with the post or rod M acting to resist rotation of theclamping 30 member relative to the handle I.

The post or rod I4 is elongated in shape, as shown more particularly inFig. 3 oi. the drawings, and extending from the outer end thereof is aplate or extension indicated at 15 provided 35 with the flat surface l6from which projects vertically spaced aligned screws l'l, adjacent oneside edge, and a single screw 18 adjacent the opposite side edge.Received on the vertically spaced aligned screws 11 is the arm portionIQ of 49 a clamp jaw 20 formed in its inner edge with a groove 2| asshown more particularly in Fig. 4

of the drawings. Pivotally mounted on the upper screw "is a plate or arm22 formed on its free end with an outwardly directed flange or pro- 45jection 22 forming a finger grip for operating the plate or arm. The armI! is secured on the screws H by means of the cap nuts 24, the inneredges of which engage the washers 25.

Pivotally mounted on the single screw I8 is 50 the arm 26 of theclamping jaw 21, this clamping jaw 21 being formed in its inneredge'with a groove 28 corresponding to the groove 2| in the clamping jaw20. Adjacent its inner end the arm 26 is formed with a screw threadedopening 55 similar to the opening 29 shown in Fig. 11 of the drawingsandin which is threaded the screw 20 having the enlarged head portion bymeans of which thescrew may be operated, it being noted by referencemore particularly to Fig. 1 of the drawings that the inner end of thescrew ll engages the inner edge of the arm ll of the clamping'jaw and asthe screw 2| is rotated the arm 26 will be swung on its pivot screw llto move the clamping jaw 21 towards or away from the clamping jaw 20. Asnoted more particularly in Fig. 1- of the drawings the pivoted by thecap screw 32 received on the screw I8.

The inner end of the post or rod i 4 is formed with an opening 34, andthrough which extends the screw 35 having the head portion 38. Thescrew, adjacent the head portion 38 is round, as

. shown at 21 while the remaining portion is flattened as shown at 28.The rounded portion 31 of the screw passes through the opening 34 of thepost or rod l4 while that portion of the screw having the flattenedsurface 38 passes through the semi-circular opening 4 of the wall orpartition 2 of the handle I. This construction prevents rotation of thescrew relative to the handle. A cotter pin is shown at 39 and extendstransversely through an opening formed in the screw 25 at the end of thepost or rod. This cotter pin prevents sliding movement of the screw inthe end of the post or rod. Surrounding the screw 35, and positionedwithin the flange or sleeve Ii of the handle I is a flexible sleeve orpacking 40, preferably of rubber, the inner end of this sleeve orpacking 40 engaging the wall or partition 3 as shown more particularlyin Fig. 3 of the drawings. A metal cap 4! is received on the outer endof the sleeve or packing 40 and is engaged by a nut 42 received on thescrew. As the nut 42 is adjusted it will flex the packing to a greateror less degree and this packing normally tends to force the nut 42 andscrew 35 outwardly to tightly engage the head 36 of the screw with theend of the post or rod i4 and thereby actingas a resistance againstrotation of the rod or post relative to the handle I.

At 42 I have shown a section of cable to be spliced and, as shown, aloop is provided in which is received a thimble 44. This thimbleencloses or surrounds a part of the circumference of the cable while theremaining circumference thereof will be received within the grooves 2|and 28 of the clamping jaws 20 and 21 as shown more particularly in Fig.4 of the drawings. As shown more particularly in Fig. 1 of the drawingsthe screw 20 will be operated to securely clamp the end of the cablewith the thimble within the clamping jaws, and it will be noted that asulficient portion of the circumference of the strands of the cable isexposed outside of the groove of the thimble to permit the clamping jawsto properly force the cable into tight engagement with the thimble. Inother words if the jaws of the clamping members engaged the thimbleitself as distinguished from the cable the clamping engagement would belimited and the proper clamping action prevented. Connected to thethimble 44, by the eye 45, is a turnbuckle rod 46 which while splicingor wrapping extends parallel between the inner edges of the arms l9 and2.6 01

the clamping laws and is prevented from swinging outwardly from the faceof the plate II by the arm or plate as will be readily apparent byreference to Fig. 1 of the drawings.

The arm I! of the clamping jaw 2| 'is shown as provided with a notch. 41which is used as a gauge for determining the proper-clamping jaws to beused with a particular diameter of the cable. The cable. of properdiameter may be'received in the notch 41 and thus the proper clampingjaws to be used determined. I

InFlg. 11 of the drawings 1 have illustrated a slightly modifled pair ofclamping jaws shown at 4l-and 4! these jaws including the arms 50 and llhaving the openings 52 and 53 respectively adapted to be, received onthe-screws l1 and I4 extending from theplate It.

It is thought that the construction and operation will be clearlyunderstood from the above detailed description. 'It will be seen that Ihave provided a device whereby either flexible or nonflexible cables maybe spliced or wrapped and in which there are readily removable andinterchangeable clamping jaws adapted for use on cables of varioussizes. At the same time the clamping jaws are carried by a memberrotatable relative to a handle portion and when the handle portion isclamped in a vise or the like the jaws or carrying member may be turnedor rotated slowly ping takes place means are provided to resist theturning or rotating action to prevent the twisting cable from causingthe jaws to fly. back as the work progresses, this means including theyieldable portion 9 adjusted by the screw [2 to engage the post orrod l4and the flexible sleeve 40 and screw 35 adjusted by the nut 42.Non-flexible cables are generally wrapped instead of spliced. For thisoperation it requires a clamp with strong jaws and by providing thereadily removable and interchangeable jaws, as previously described, mydevice is adapted for use in splicing flexible cables or in wrappingnon-flexible cables. The shapes of the clamping jaws match exactly theform of the thimble, within the loop of the cable, thereby facilitatingoperation and permitting a high grade of workmanship.
